Monochorionic twin pregnancies are at increased risk of adverse outcome because of the vascular anastomoses that connect the 2 fetal circulation systems. The shared circulation is responsible for some unique complications in monochorionic twins, such as the twin-to-twin transfusion syndrome, the twin anemia polycythemia sequence, the twin reversed arterial perfusion ...

Background: It is often assumed by obstetricians, neonatologists and parents alike that the prenatal nomenclature used to identify twins on ultrasound is consistent with twin labelling after their birth. The aim of this study is to use a large regional twin ultrasound database to validate the effectiveness of a scan ...

Experimental and animal data suggest that maternal obesity during pregnancy adversely affects offspring health in the short-term and the long-term. Whether these effects occur in humans and influence population health is less clear. This Review explores evidence from intervention studies and observational studies that have used designs (such as family-based ...

Monochorionic (MC) twins represent a significant proportion of perinatal morbidity and mortality. Overall, 1 of 3 MC twin pregnancies will develop complications in relation to the MC placenta and the presence of interfetal placental anastomoses. From a clinical standpoint, these complications can be grouped into four main types of clinical ...

Hemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening inflammatory disorder characterized by uncontrolled proliferation and activation of histiocytes with phagocytosis of normal hematopoietic cells. A 41-year-old woman, 19 weeks pregnant with twins, and a history of Still's disease, presented with rash, fever, and headache. Laboratory studies revealed transaminitis, hyperbilirubinemia, and eventually ...

Newborn screening for congenital hypothyroidism has been remarkably effective, although rare cases of false negative screening have been reported in same sex twins, presumptively due to fetal blood exchange. We report a case in which the diagnosis of congenital hypothyroidism due to thyroid ectopia in a monozygotic twin was delayed ...

Since its inception in 1983, the Wisconsin Stillbirth Service Program (WiSSP) has reviewed over 2,600 referrals. Among 2,451 with fetal weight and gestational age recorded, 186 (7.6%) were large for gestational age (LGA), which is more than expected. We reviewed these cases to identify factors causing or contributing to fetal ...

Malawian women in all sectors of society are suffering from social implications of unwanted pregnancy and unsafe abortion. Unwanted pregnancies occur among women who have limited access to family planning and safe abortion. A legally restrictive setting for safe abortion services leads many women to unsafe abortion, which has consequences ...

Twin pregnancy differs considerably from singleton pregnancy in many aspects and it is unknown how serum NT-proBNP level behaves in women with twin pregnancies. Serum NT-proBNP levels were determined longitudinally at gestational weeks (GW) 24 and 35 in normotensive women with 13 twin and 99 singleton pregnancies. The effects of ...

Abstract A review of the literature on maternal weight gain in singleton and twin pregnancies has identified two main messages. Firstly, that very little robust evidence exists on which to base advice to mothers about appropriate weight gain during pregnancy. Evidence that does exist has tended to be observational, or ...

Familial severe hypertriglyceridemia (levels greater than 1000 mg/dL) is a known cause of acute pancreatitis. Pregnancy can dysregulate controlled lipid levels in women with familial hypertriglyceridemia and lead to acute pancreatitis and significant morbidity in both mother and fetus. We report a case of hypertriglyceridemia-induced pancreatitis during pregnancy that was ...

OBJECTIVE: The optimal gestational duration for twin gestations is unknown. Epidemiologic studies show that the lowest perinatal mortality rate for twins is at 37-38 weeks, but these studies lack information on pregnancy complications and neonatal morbidities. This study evaluates pregnancy characteristics and perinatal outcomes of twins in order to assess ...

Heterotopic pregnancy describes the relatively rare coexistence of one or more intrauterine gestations and one or more extrauterine (ectopic) gestations. We describe a unique clinical case involving successful treatment of an ovarian heterotopic pregnancy through gestational sac aspiration and injection of hyperosmolar glucose. A 31-year-old woman presented with an ovarian ...

It is generally accepted that progesterone (P4) is a key regulator of reproductive function in mammals. In cattle, the primary focus of P4's actions has been uterine receptivity and maintenance of pregnancy. Studies in mammalian laboratory species and ovarian derived cell lines also highlight their role in ovarian function. Extensive ...

The modern domestic sow exhibits a period of impaired reproductive performance known as seasonal infertility during the late summer and early autumn months. A reduction in farrowing rate due to pregnancy loss is the most economically significant manifestation of this phenomenon. Presently, little is known of the aetiology of seasonal ...

Mammals such as cattle, swine, sheep and humans are born with a highly variable number of ovarian follicles and oocytes in the ovaries that dwindle during ageing and are never replenished. This variation in the ovarian reserve is reflected in the numbers of antral follicles in the ovaries at all ...

We sought to estimate the association between chorionicity and intrauterine fetal demise (IUFD) of one or both fetuses in twin pregnancies. In a retrospective cohort of twins undergoing anatomic survey, risk of IUFD in monochorionic and dichorionic twins was compared. The primary outcome was IUFD of one or both fetuses; ...

Monozygotic multiple pregnancies are three times more common after assisted reproduction (with or without IVF) than after spontaneous conception (1.2% versus 0.4%). These pregnancies are associated with multiple maternal and fetal risks. This article is a description of nine cases of monozygotic pregnancies following IVF at the OVO Clinic (Montreal) ...

Primary ovarian ectopic pregnancy (OEP) remains a rare but important type of ectopic pregnancy which is normally diagnosed at surgery. The aetiology is unknown. We have found fertility treatments (18.1%) and intrauterine contraceptive devices (19.3%) remain important associated risk factors. We undertook a world literature review of all cases since ...

A 30-years-old Taiwanese female in her second pregnancy spontaneously conceived a monochorionic twin pregnancy. A routine ultrasound at 27 weeks of gestation revealed a selective intrauterine growth restriction (sIUGR) fetus and an appropriate gestational age (AGA) fetus. The AGA fetus was found to have a fetal intra-abdominal umbilical vein (FIUV) ...

Despite the fact that ovarian stimulation is controlled, it is not always predictable. Because the day of human chorionic gonadotrophin (hCG) injection depends mainly on the patient's ovarian response to gonadotrophins, the day of oocyte retrieval cannot be determined in advance. As a result, oocyte retrievals are often scheduled to ...

Trisomy is the most common type of chromosome abnormality, affecting 4% of clinically recognised pregnancies, of which, trisomies 16, 21 and 22 are the most prevalent. It has been suggested that a large proportion of maternally derived trisomic pregnancies, specifically trisomy 21, are the result of low-level ovarian mosaicism. In ...
